How to interpolate impedance measurements in a polar plot

Hello,
I do impedance measurements and plot them afterwards in a polar plot (see attached VI). Because of a sharp resonance it is hard to get a high resolution there.
- Is it possible to do an interpolation between the the measured points?
Thanks a lot.
Best regards,
Michael

Take a look at the attached. I created an array to resample the data based on the data itself and then used the Resample (constant to variable) to generate interpolated data. This way the resonance is interpolated with more resolution than other locations. Does this do what you want?
There is a constant on the block diagram that controls how much more the resonance will be interpolated.

How can I increase line width on polar plot?

The lines plotted on a LabVIEW 6 polar plot (picture control) are very thin and do not show up well when printed. I would like to increase the line thickness (as can be done easily on the graph controls), but looking through the polar plot VIs, I cannot find any obvious way of doing this.

The polar plots basically use the picture control to draw the lines on a plot. To increase the thickness of the lines you would have to draw another line right next to the line. I'm sure this could be done, but would require alot of messing about with the drawing subVI's to draw all lines in duplicate.
Alternatively you could plot the graph twice, but the second plot has an origin 1 pixel out. This will double the thickness on the screen, but i dont know what it will print out like. See attached example in LV 6.0.
Another thing to try is change the plot colours. You can make the gridlines black (instead of grey), and paint the background white. This makes the lines show up much better. I will also include this in the same example.
I hop
e this helps you..

How can I change the Y-axis (circular) grid spacing, in Polar Plot VI?

When using Polar Plot VI, I need more control over the plotting parameters. This means tweaking the sub-VIs in various ways. What I need to do most is make the polar magnitude axis less busy, i.e. only draw circles every 10 instead of every 5 divisions, when using a range of 0 (outermost) to -80 (innermost).
The magic 'magnitude axis subdivisions' variable seems to be generated in Calc Scale Specs sub-VI, and output as an array of clusters, but I can't quite see how it's created and from what.
Please can anyone help me gain control over the number of magnitude division circles generated?
Many thanks!

I think if you go inside the Calc Increment.vi and modify the Increment output terminal it might change what you want to see. Try putting a multiply by 5 or ten into the case structure for when the log is false.

How to control the measure based on the related dimension.

Hi Experts,
In order to improve performance, I have created three kinds of time tables in DB,such as Year .Month, Day.
Then import them into the physical layer in RPD, and combine them into one dimension in BMM.
Actually, it has three level fact related with three time tables,so they are also dragged into one fact in BMM,and one column will be corresponding with three column derived from different Fact table in physical layer.
So I want to know how to control the measure based on the related dimension.
For example:
when users drag the Year,Sales column, it will come from Year Dimension and Year Fact Table.
when users drag the Month,Sales column, it will come from Month Dimension and Month Fact Table.
when users drag the Day,Sales column, it will come from Day Dimension and Day Fact Table.

Hi,
Create a dimension Hierarchy, with Year >> Month >> Day Levels and
Next Double click on Year Table LTS >> click on Ocntetnt Tab >> set as Year
same way for Month LTS and Day LTS.
So now when you select year column then server canknow which LTS to hit and Hits Year LTS.

Thanks.

How to create a measure for COUNT and compare year-to-date/last year?

Hello expert,
I have gone through the Oracle by example tutorial for creating the repository. However, I can't find out how to create a measure to display the COUNT (sequence ID). I tried the Aggregation function on the sequence ID on the Fact table but the report on Answer listed out all the sequence IDs in the database. And did not give me the count of the transaction for the period quarter. If I used the sequence ID on Dim table, the SQL failed.
And also I want to have two counts, one is for the count of transactions by quarter. Another is for count of transaction for the same period quarter.
Please help.
Thanks.....

If you use count (or count distinct ) as the aggregation rule in the dropdown in the repository column, it should work. Or you can post the generated logical and physical sql here.

How to draw polar plot?

Hi all,
I want to draw a polar plot in LV. I am having different values of frequencies & voltage/current values at respective freuencies. Can anybody guide me?

Hi Vaibhav,
LV already has a polar plot indicator and comes with an example of how to use it...
Btw. usually you plot a signal vs. phase on a polar plot. How would you plot vs. a frequency?

How to combine several measures into 1 pie chart

Hello everyone,
I have a requirement to create a design studio application with a pie chart to show several measures.
It means that I have several different measures and I want to let each piece of the pie chart present 1 measure.
For example, I need to combine measure1 ,measure2, measure3(which correspond KeyFigures in Bex query) into 1 pie chart and there should have 3 pieces.I tried change swap axis option and put all measures into row, not works.
I am very appreciate if anyone could help. Thanks a lot.

Hi !
There is a tricky way to do that.

How does Activity Moniter measure Network speeds.

How does Activity Monitor measure network transfer rates? They are always much lower than Web based speed checks. Typically my download speed on Activity Monitor is 162 KBS whereas Web based speed check return 1.2 MBS.

Duh! I should have realized the AT&T and Activity Monitor are using two different measurements. AT&T uses bits. Activity Monitor uses Bytes. Multiply Bytes by 8 to get bits. So 162 K-bytes in Activity Monitor = 1.29 M-bits in AT&T speed test. The problem comes in misreading the labeling of the units measured. Which is something that causes confusion frequently because the industry is not uniform in its use of labels.
It is interesting that AT&T uses the higher number. Is this a marketing strategy? Don't get me wrong, I am very satisfied with their service.
I am also VERY satisfied with my MacBook Pro. The best Mac I ever owned (since my first Mac in 1993 and Apple 2's for 10 years before that). Awesome system software, boots faster than previous MacBooks I owned. Has been flawless in performance. I bought it from Apple refurbished. It came with a larger HD than I ordered. I have used both WinTel (since 1993) and Apple machines. There is no comparison IMHO.

How does Order Analysis measure phase lag, particularly super-sync amplitudes?

In recent testing of a high speed gear box, an 8X amplitude was observed (on the radial displacement probes) as the gear passed through a certain speed range. An NI4472 pci card and vi's written in 7 Express, w/ Order Analysis tool kit were configured with radial displacement probes and keyphasor as input signals. The behavior of the phase lag measurement is significant. If the phase lag of the 8X amplitude rolled as the gear passed through a particular speed range then this could suggest one particular problem, but if the phase lag remained constant then this could indicate a different problem. So, someone asked: How does the system measure phase lag of supersynchronous amplitudes?

See attached file for figure 1,2,3
The Phase measurement in the LabVIEW Order Analysis Toolkit uses the phase lag convention. Phase is defined as the angle difference measured from the peak of a vibration signal backward in time to the reference trigger point. This means the directions of numerically increasing angles are always set against the shaft rotation. The trigger point here is the tachometer pulses.
Figure 1 shows the relationship of the vibration signal and reference signal to zero degree phase. The shaft has a heavy spot and a keyway slot. When the keyway slot passes the tachometer, the tachometer detects a trigger pulse. The heavy spot causes the shaft to vibrate as the shaft rotates. When the heavy spot passes the proximity probe, the vibration reaches a peak. When the heavy spot passes the proximity probe and the keyway slot passes the tachometer simultaneously, the peak of the vibration does not lag or lead the reference trigger point. At this point the phase is zero degrees.
The other part of the convention dictates that 90 degrees means that the peak of vibration lags 90 degrees behind the trigger point. Figure 2 1illustrates the 90 degree phase. When the vibration signal reaches the peak, rotate the shaft backward (counter the rotation direction) until the keyway slot passes the tachometer. The number of degrees you rotate is the phase lag, or the phase value in machinery vibration measurement. Figure 2 shows the relationship of the vibration signal and reference signal to the 90 degrees phase convention.
For the 8x phase, the measurement is conducted in the similar way. The difference is that the 8x order component go 8 times faster than the trigger pulses. Figure 3 shows the 90 degree phases ( tacho pulse in rising edge) of the 8x order components. The phase measurement is still conducted through calculating the delay between the peak in the 8x vibration components and the trigger pulses and comparing the delay to one cycle of the 8x components. In figure 3, the signals between the two green grid lines are used to output one phase results.

How does MID-7604 measure peak current?

What are the details about how the MID-7604 measures and regulates motor winding current?
We manufacture motion systems incorporating small step motors. One of our customers has ordered a motion system with the MID-7604. This is our first experience with the MID-7604.
When duplicating motor performance comparable to our other Step-motor Controllers, we must set the MID-7604 to 3X the motor's traditional rated peak current. For example, for a super-small MicroMo/Arsape Step motor, we traditionally limit the current to 250mA (RMS). However, with the MID-7604, we must raise the current limit to 700mA (peak) to achieve the same performance.
While we're not sure about the current regulation philosophy of our other Step-motor Controllers, the Step-motor Manufacturer's Specification Sheet limits the current to 250mA per phase with both phases energized to prevent overheating. Pumping in 700mA from the MID-7604 to achieve comparable performance just seems excessive. However, we're just playing with numbers here and not knowing what they mean. In the end, we're ignoring the numbers and instead, measuring motor torque and winding temperature in order to set the peak current switches on the MID-7604.
* How can we think of the current setting for the MID-7604?
* Is it not a PWM device that using width of voltage pulses to produce the current?
* What does "PEAK CURRENT" and "RMS CURRENT" mean?

Hey JThomas,
I'm sorry to hear that you smoked a stepper motor.There are a couple of reasons that your MID-7604 drive could appear to be operating strange.
There is a series of DIP switches on the front of the MID drive that allow you to set various things. One of those DIP switches is the current reduction switch. This switch is default in the ON position from the factory I believe so if it has never been turned off, chances are it's ON. When the Current Reduction switch is active, the stepper drive drops the current energizing the coils by 50% if there hasn't been a step in the last 500 ms. If you were gauging the strength of the drive based off of holding torque, then this could be the reason you were raising the current to a higher rating than you thought was neccesary. This settings is for customers who have an application with stepper motors that focus more on moving torque instead of holding torque.
Another possible reason for the increased current to match performance of your drives is if the bus voltage of your drives is some voltage other than 24 VDC. If your drives that you are used to using are say 36V drives, then at a lower current setting, they would provide greater torque at higher speeds because of the higher voltage being able to energize the coils faster.
Also, the KILL feature releases the axis from being actively driven. The HALT command simply locks the motor while leaving the coils energized to hold the position that it is currently in.
I hope some of this has helped you out. Let me know if I can elaborate on anything.
Thanks,

How to clear polar plot Programmatically

How to clear polar plot Programmatically, thanks!

This doesn't technically clear the plot, it's writing an array of zeroes to it. But if all you want is to make the plot appear to dissapear that's ok.
I've taken a closer look and found that you have to use the Erase First property node to set which pictures can be erased. The default is never erase any, which is why the plot doesn't clear.
Then, you can get an empty picture constant from the pictures sub-pallet and wire that into the Value (Signalling) property node and it will work.
I have attached one VI with and one without the event structure to tidy things up, but you may not have the event structure available to you. I wrote these in LV2012.

How to add cursors on polar plot

I want to add cursors on polar plot just like the XY graph has. I am new to LabVIEW and want to be able to move those cursors by mouse movements and get the respective Angle and Magnetude values. Since the polar plot is a picture I am unable to do the same. So my questions is;
Can I add cursors on Polar plot? If not, then, is there any other way to do so?

Hi!
I've found an old post about you issue: http://forums.ni.com/t5/LabVIEW/the-best-way-to-make-a-nice-POLAR-plot-in-LV/td-p/115478 (but no easy solution is provided ).
You can use an XY plot, of course, but it's up to you to convert your polar plot to the cartesian coordinate system of the XY plot and the way back for the cursor coordinates.

How do you get the polar plot VI's to work correctly?

I have the data in a file and can see the correct data when placed on a smith chart, but not on the polar plot. It looks like it is mirrored on the Polar plot.

There are a couple of examples hat come with LabVIEW that might help you. They can be found under Help >> Examples >> Advanced >> Picture Control >> "Polar Plot" and "Simple Smith Plot". As a way of comparing the two different plots, I had them plot the same data points. It looks like if you have a lot of data points with a lot variability then you want to use the Polar Plot. The following webpage may provide some infor regarding smith plots:

How do u modify polar plots

I would like to modify/control as many features on a polar plot as possible. I am aware of the property node feature, but those seem to be limited in what can be modified. I would like to have control over plot line thickness, fill-in solid color under data, and text size. I have seen these things modified before but I can't figure it out myself. Has anyone had this same issue?
Thanks!

robin533,
It sounds like with as much customization as you want, you might have to dig deep in the code. I would suggest trying to get into the low level code of the Polar Plot VI and seeing if you can modify what it is you're looking for. You can access some pen controls and color options this way.
Cheers!

Polar plot for antenna measurement

Hi,
I have LabVIEW 8.2 (Full) and I could make a polar plot in LabVIEW from the 'Polar Plot.vi'. However, I realized that I don't have the option to use 'Create Annotation' on the front panel to get the value of certain point of interest on the plot itself (since the plot itself is a picture). My point of interest is -3dB from the peak of the plot, and is there anyway to extract the corresponding information from the polar plot? Eg, peak point is -20dB, my point of interest would be -23dB, and I would like to retrieve the angle of -23dB.
Attachments:
polar.vi ‏32 KB

I must have attached the old file. I did use the 'Array Max & Min.vi' to look for the highest point in dB, and then get the corresponding angle. From the max point, I subtracted 3dB and obtained the -3dB point, but there is no corresponding value for the -3dB point. Eg: -20dB is the highest peak, -23dB is the point of interest, and there is not -23dB in my data set. In other words, I might have -22dB, -22.5dB, -23.3dB etc
I am assuming that the 'Polar Plot.vi' will connect all those points together and form the polar picture. And I would like to obtain the -23dB angle from the plot.
